The invention relates to an airport enclosure anti-intrusion alarm system. The system comprises a front-end detection subsystem, a monitoring command center subsystem, a video monitoring subsystem, alinkage control subsystem, a network transmission subsystem, a power supply subsystem and a weather station subsystem; and the front-end detection subsystem, the monitoring command center subsystem, the video monitoring subsystem, the linkage control subsystem, the network transmission subsystem, and the weather station subsystem are all connected with the power supply subsystem through wires. Theairport enclosure anti-intrusion alarm system of the invention is an anti-intrusion system which is constructed based on the Internet of Things technology and a physical enclosure; the system can accurately and timely report intrusion anomaly events, send an alarm to a monitoring center, achieve target positioning and accurately record alarm time, positions and images. According to the airport enclosure anti-intrusion alarm system of the invention, various kinds of anti-intrusion means are adopted to realize cooperative and comprehensive detection, and therefore, the shortcomings of the monotony, high false alarm rate and poor security of traditional detection means can be eliminated; and the weather station subsystem is adopted, and therefore, all-weather and all-day detection performance can be improved.
